Domain wall dynamics in Fe-rich glass covered amorphous microwires

The influence of glass covering on domain wall propagation in Fe65B15Si15C5 amorphous microwires is studied, before and after glass removal. High values of domain wall velocity and mobility have been obtained. The domain wall velocity depends linearly on the driving magnetic field. However, the mobi...

Description
Summary:The influence of glass covering on domain wall propagation in Fe65B15Si15C5 amorphous microwires is studied, before and after glass removal. High values of domain wall velocity and mobility have been obtained. The domain wall velocity depends linearly on the driving magnetic field. However, the mobility of the domain wall is very different in both situations studied. The results are explained due to the modification of internal stress distribution after glass removing, that change the domain structure of the sample. (© 2009 WILEY‐VCH Verlag GmbH & Co.
